شبهگونههای تریکودرما از مهمترین آنتاگونیستهای قارچهای بیمارگر گیاهی میباشند که شناسایی و تعیین توان آنتاگونیستی آنها کمک زیادی به مطالعات کنترل زیستی میکند. هدف اصلی از این مطالعه تعیین توان کنترلزیستی جدایههای بومی تریکودرما، جدا شده از مزارع چغندرقند، علیه گونههای phytophthora drechleri و p. cryptogea عوامل پوسیدگی ریشه چغندرقند میباشد. طی دو فصل زراعی (1386 و 1387)، 85 جدایه از گو...
A pot experiment was conducted with the single and combined doses of fungicides, plant extracts antagonist for management nine rice pathogens. total 13 treatments including controls or without inocula pathogen were tested. Amongst all only T6 (Bavistin + Azadirachta indica Trichoderma harzianum) showed highest percentage seed germination seedling vigor index seeds inoculated Alternaria alternat...

Different species of Trichoderma especially T. harzianum (Th2 biotype in Europe and Th4 in America) considered as causal agent of green mould disease on button mushroom (Agaricus bisporus) casing beds. In this study, 100 fungal isolates were collected and purified from different mushroom growing units in Tehran province and Urmia (NW Iran). Totally, 60 isolates of T. harzianum, 27 isolates of T...

abstract pythium aphanidermatum is one of the most important agent of root and foot rot of cucumber, particularly in the warm humid climate. induction of host resistance by microorganisms or by the synthetic compounds is recently considered as one of the biological control method of disease. trichoderma harzianum bi is a good candidate for induction of resistance in plant against diseases. the ...
Trichodermanins C-E (1-3), new diterpenes with a rare fused 6-5-6-6 ring system, have been isolated from a fungus Trichoderma harzianum OUPS-111D-4 separated from a piece of a marine sponge Halichondria okadai, and these chemical structures have been established by spectroscopic analyses using IR, MASS, HRFABMS, and NMR spectra. We established their absolute stereostructures by application of t...
